Questione giuridica chiave
Whether Swiss courts had jurisdiction for provisional debt-enforcement release despite a contractual forum clause.
Decisione estratta
The provisional release procedure falls under Art. 16 No. 5 LugÜ and its jurisdiction is mandatory; the parties cannot derogate from it by agreement.
Motivazione estratta
The procedure is closely tied to enforcement, not to adjudication of the underlying claim. Because Art. 16 LugÜ jurisdictions are exclusive, a forum clause cannot exclude the Swiss enforcement forum for provisional release.
